Covering key aspects of provenance research for the international art market, this accessible publication, co-published with the International Foundation for Art Research (IFAR), explores a range of themes including challenges and best practice to considerations specific to Nazi looted art and the trade in illicit antiquities. Provenance research is a crucial component of any art-market transaction. Without a provenance it is often difficult to establish a work's authenticity, its true value or who has legal title. Whether buying, selling or simply maintaining an artwork in either a private or a public collection, the days when a blind eye could be turned to the history (or the lack of a known history) of a work have long gone. Proper, thorough and effective provenance research is the minimum required and demanded in today's art world - a world that is increasingly recognizing the need for greater and more effective self-regulation in the face of fakes, forgeries and challenges to ownership or authenticity that are now commonplace. Provenance Research Today is essential reading for a broad audience, from those studying to become part of the art world or professionals starting a career in provenance research, to collectors or would-be collectors, dealers, galleries, auction houses, police and art lawyers.
